.M M NLnaHsEnnE j p Ap lica io iel w 1 to the trough for supportingjan arche-d cover 'to comprise a pipe casing, the principal objects of'the invention being to facilitate the connection of trough sectionsand mountlng of cover. supporting flanges, andto reinforce the connection oftrough sections incidentally to mounting the cover-supporting flanges. 'In accomplishing these and other objects ofthe invention, I- have provided improved details of structure, the p'referredfor ns. of which areillust-rated in the acco npanying drawings, whereint Fig. l l-is a perspective view of portions of a conduit in a: trench, a cover-supporting flange member being shown in spaced rela-f tion with trough sections on which it is adapt- V J keeper flanges 14 at; the ,innergedgeis of thel ed tobe mounted.

Fig. 2 is a cross section of the completed conduit with steam pipes and insulation enclosed thereby.

Fig. 3 is an enlarged perspective view of a rivet-equipped end of a. trough section.

Fig. 4 is a similar view of the opposite and slotted end of a trough member.

Fig. 5 is a longitudinal section of portions of adjacent interlockingly engaged trough sections, illustrating rivets of one section engaged in slots of the other section.

Referring in detail to the drawings: 1 designates generally a conduit adapted to be erected and installed in a trench 2 and including sheet metal base or trough sections 3 adapted to be arranged longitudinally in the trench in telescopingrelation, and bracket-like flange members 4: comprising plates supported by the trough sections and having channel-like outwardly extending seats 5 at their lower edges. An arcuate cover 6 has lower edges mounted in the channel seats and is adapted to be secured to the trough sections by wires 7 attached to the outer flanges of the flange members, all of which will be more particularly described.

The trough sections 3 comprise floors or 'I'Eachi rivet; 11, includes. a

A suitable number of cover-supporting brackets or flange members may be mounted on the trough sections, and assembled and fixed thereto by the rivets'described, for installing a considerable section made up of elements described in a trench. a,

A second assembly may be made up and of the first named and second named assemblies may easily be connected by means of the rivets adapted to move into the slotted ends of trough sections and the relatively easily installed flange members.

The trough structure is particularly adapted to receivetubes such as 18 and 19 comprising steam pipes mounted on rollers 20, and insulating-material 21 installed to cover I the tubes' The insulation will be-securely retained by the cover latched by the wire anchored to the-flange members.

What I claim and desire to secure by Lett ers Patent isz I -1.In 'a conduit of the character described 7 including a series of aligned trough sections having upstanding sides, and means for connectingthetrough sections, flange brackets aboutthe rivet.

including'inwardly bent flanges adapted to "overlie adjacent ends of trough sections,and means for latching one of said flanged brackets to'adja'cent trough sections includintroduced to the trench and the'related ends engageable over the sides of aligned sections a rivet in one of said sections engageable in said slot, and means for securing said side member to the other of said sections.

5. A conduit including a pair of aligned sections having upstanding sides and end slots, rivets adjacent the end of one of said sections to engage in said slots in the adjacent H end of the other of said sections for latching said sections in overlapping relation, a side member having amend slot and an inbent edge flange forming a hook to engage coincidently over substantially aligned sides of said sections,.a rivet in one of said sections engageable in said slot of the side member, and means for securing theside member to theother of said sections. 7 p

6. Ina conduit,trough sections in end to end telescoping relation and including bottom and sidewall portions, adjacent sections having respectively a longitudinal end edge slot and a rivet engageable in the slot upon longitudinal movement of the adjacent sections toward each other into telescoping rela- .tion for latching the sections against lateral movement, a bracket having a flange to engage coincidently over adjacent side wall portions oifadj acent sections, and means for securingthe bracket to said adjacent side wall portions for retaining the latched ends of said sections agalnst vertical movement.
